MACHINE FOR DE LLINTING COTTON SEED.

SPECIFICATION forming part of Letters Patent No. 384,340, dated June 12, 1888. Application filed February 8, 1888. Serial No. 265,637. (No model.)

To all whom, it may concern:

Be it known that we, J AMES L. XVEATHER- HEAD and J Anus S. COOl-IRAN, citizens of the United States, residing in thecity and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Machines for Delinting Cotton-Seed, of which the following is a specification.

Our invention relates to improvements in machines for delinting cottouseeds; and it consists in providing the same with an inside cone having a beveled or inclined upper end, whereby a chamber of down wardly-increasing width is formed for the purpose ofseparating or breaking up the masses of seed bet'orethey pass into the dclinting portion of the device.

This improvement is fully shown in the accompanying drawing, which represents a broken vertical sectional view of a machine for delinting cotton seeds embodying our invention.

Referring to the drawing, A represents a hopper secured on the upper portion of the frame A of the machine, and opens into the stationary conical casing 13, which is secured in place to the frame A. One portion of the conical casing 13 is composed of a door part, 0, which is so secured to the other portion as to admit of its being swung outward in a horizontal direction. The means employed for this purpose consists of a hinge, a, the members of which, respectively, are secured to the lower portion of the side of the door and to the other or main portion of the cone, and a hinge, a, the members of which are secured at the upper side portions, the members of the hinge a being made larger than those of the hinge a, so that the pins of said hinges shall stand in the same vertical line, and the door will readily swingiu ahorizontal direction and remain in place when opened without a fastening device.

D represents an inner revolving cone mounted on the vertical shaft E, the latter being suitably iournaled in the frame of the machine and provided with the. pulley F, by means of which rotary motion can be communicated to said shaft and cone from any suitable motor connected thereto by proper mechanism. The upper end of said cone D is rounded off or beveled, or tapering toward the axisat a greater angle than the lower portion of its height, whereby a chamber, 0, is formed between the cone D and the conical to the metallic brushes G, the wires whereof being attached to long strips of leather or other suitable material, the strip being preferably wound spirally on the inner cone, and the brushes on the inner sruface of the outer cone extending above the top of the inner cone. The chamber 0 constitutes a downwardlycontracted or tapering; seed-receiving chamber having bruslrelothed opposite walls.

The operation is as follows: The cotton-seed is fed into the hopper A of the machine, falling on the upper end of the cone D, when, owing to the centrifugal motion of the shaft E and cone, it is forced or thrown against the brushes on the upper portion of the cone B, working down through, and falls into the chamber 0, in which the masses of seed are separated, so that they readily and uniformly pass therefrom between the brushes of the lower or delinting portion of the machine. As the seed and lint reach the bottom of the cones they are discharged therefrom, and may be separated by any usual device, as a fan or blower, such means being common and well known, and, not being claimed per se herein, are not shown in the drawing.

Having thus described our invention, what we claim as new, and dcsi re to secure by Letters Patent, is-

The combination, with the conical casing B, having its interior surface clothed with brushes, as described, of the cone D, having its exterior surface clothed with brushes and having its upper portion rounded off or tapered toward its axis at a greater angle than the lower portion of its height, as described, and thereby forming between the said cone and easing a downwardlycontracted or tapering seed receiving chamber having brushclothed opposing walls, as described, providing for the separation of the seeds and facilitating their entrance between the acting surface of the cone and easing, substantially as described.
